Our Products

NovaFlex® Silicone Sealants

The products of the NovaFlex Series are non-corrosive, single-component, modified oxime cured silicone sealants and adhesives which are used most frequently within the window and door manufacturing industry as glazings and structural back-beddings. The NovaFlex products are available in a broad range of standard and custom color formulations. NovaFlex products will develop primerless adhesion to most common construction substrates and the neutral cure is compatible with most materials.

NovaFlex® SB

A patented Novagard innovation, NovaFlex SB was manufactured to compliment any type of glazing rabbet profile design. Novagard combines modified oxime cure technology with consistently sized spacer-beads to provide a “liquid shim” primary bedding seal on wood, PVC, fiberglass and aluminum. The bead assures controlled compound thickness between the glass and the sash, which will maximize sash performance while minimizing sealant consumption. It also eliminates squeezeout, which provides for easier re-glazing. Tailor your SB product with a specific spacer-bead size and your choice of cure rate, viscosity, green strength, physical properties and color.
